@laukanhenkka Google is a publicly-traded corporation with a fiduciary duty to its shareholders.
They cannot just give some organisation half a billion dollars unless they can make the case that they’re getting more than half a billion dollars of value back from their investment.
Most visibly, Mozilla makes Google its default search engine on Firefox.
More than that, Mozilla gets to exist thanks to Google. No half a billion a year from Google, no Mozilla, no Firefox.
